Abstract : Many devices that employ magnetic fields have heretofore been encumbered by massive solenoids with their equally bulky power supplies. Thus, there has been increasing interest in the application of permanent magnet structures for such uses as electron beam focusing and biasing fields. The current demand for compact, strong static magnetic field sources that require no electric power supplies has created needs for permanent magnet structures of unusual form. A number of configurations have been designed and developed for electron beam guidance in millimeter-wave microwave tubes of various types; for dc biasing fields in millimeter-wave filters, circulators, isolators, striplines, and so on. Patent applications. (JES)
